Sanl Francisco, fornia Calif., `a 'corporationpf Cali This invention relates generally to power .operated machines for use by commercial` beauticians. vWhile various types of toolsv or instruments can be employedl with the machine, it is .35 of particular utility in carrying out `manicuring operations.

It is a primary object of the inventionto vprovide a machine of the above characterwhich can be utilized Without risk of pain or discomfort 10 to the subject.

Another object of the invention is-to provide a machine having its operating parts assembled in a novel manner, whereby the machine Vis compact and portable, and is at all times convenl iently available for use.

Further objects of. the invention will appear from the following description in which the preferred embodiments of theinvention havebeen set forth, in conjunction with the `accompanying f drawings.

Referring to the drawings:

Fig. 1 is a sideeievational view,.showingthe complete apparatus incorporating thegpresent invention.

y Fig. 2 is a plan view ofthe base plateutilized in Fig. 5 is a detail, on an enlarged scale,.,showing the reciprocating block utilized in the deviceof Fig. 4, and also illustrating the manner in which tools are releasably held by. such block.

Figs. 6 and 7 are viewsillustrating l.various 40 manicuring tools, which can be utilizedwith the device vof Fig. 4.

Figs. 8, 9 and 10 illustrate use of themachine in pushing back cuticle, and demonstrates the"` mankner in which amplitude of reciprocation, Vvaries, in

45 accordance with the restraint placed upon the tool. y Referring rst to Fig. 1, the machineconsists of l a stand IIJ, in conjunction with the pneumatically operated device I I. The .base portion of the stand includes a base .plate I2, to which theshell I3, is secured. Extending upwardly' from the shell I3`, there isa tubular upright "I4, the'upper end of which carries'a casting I5. This casting is formed to provide a handle I6, by means of. which the machine can be lifted and moved about, and

also vtohprovide-a v.bracket I1, for removablysupporting the device I I.

Mounted uponvthe base plateIZ, andwithin the shellv I 3, there is a pneumatic pulsator I 8 and an electric motor I9. The body'Zl of the pulsator Kl can be formed integral with the base plate I2, and is formed to afford a closed chamber22, one side of which is formed by the flexible diaphragm 23. The center of diaphragm 423is connected to the lower end ofa rod 24,*the upper end of which l10 connects with an eccentric Y26 lon the .shaft of motor I9. A tube21 connects with chamber 2.2,

'and is adapted to be coupled to one end of the vflexible-tube ,o1-hose .28.

.Itwillbe apparent that when motor I9 is Aop--j erated, rod.24 is reciprocated to vibrate the diaphragm I23, andthus produce periodic compression and rarefaction of.. air in chamber 22 andv in lthe tube 2 8. .By lreference to Fig. 3, it will be notedthat the flexible tube 2B extends upwardly 20 through the tubularupright I4, and is of considerable length to/enable free manipulation of the deviceY ll. Likewise electrical conductors 3| 'extend upwardly through the tubular upright I4, to

a suitable'electrical `switchf32, whereby operation 25 oftheelectrio AVmotor can be conveniently controlled.

VThe-device .II is illustrated `indetail in Fig. '4. It consistsof an elongated hollow casing Y33, of suitablematerial v.suchas avcasein plastic or a3() phenolic condensate product. 4The rear end portionofthe casing is of enlarged diameter, and includes ajclosure cap 34, which is secured to the main Abody of the casing by suitable means, such 4as a threaded connection36. Clamped between `35 the .body-of the casinguand the cap-34, there` is a exible diaphragml. While various materials can be utilized for this diaphragm, ith-can be conveniently made` of soft vulcanized rubber. Suitable coupling means 38 serve to connect the cap .140

.34 with the, flexible tube 28, whereby thisk tube is placed in communication with theclosed chamber39 on the rearside of the diaphragm 3l.

In the forward end portion ofthecasing 33, there isa block 4I, Ywhich is free to slide in' a 45 longitudinal ',direction. A'rod 42 has its forward end proy'fidedy witha pivotal connection 43 to the block 4|,jandhas' its rear end attached to the center of :diaphragm `3l. Thus as the'diaphragm 31 is vibrated by pneumatic pulsations in the 50 chamber 39, block 4I is reciprocated. Block! I ,.,isprgvided with Suitable. means to enable 'attachment' to a tool orothe'r instrument with which the machine is to be used. In Figs.

4 and 5 the tool 44 has its end portion 46, shaped 55 Cai for pushing back cuticle. The other end portion 4T of the tool is flattened and tapered to fit within a socket 49 formed in block 4|. One edge of the tool portion 41 is shown provided with a notch 5|, adapted to be engaged by detent 52. This detent is, shown being carried bya spring 53, whereby itA snaps within notch 5| as the tool is inserted in block 4|, Aand whereby the' tool can be readily detached by pulling outwardly upon the same. To secure substantially noiseless operation, the block 4| may carry a light leaf springY 54, which frictionally presses against the adjacent surface of the casing.

A side view of the manicuring tool 44 is illustrated in Fig. 5. A buffer tool 56, is shown in Fig. 6, while a nail ille 51 is shown in Fig. '7. These tools can be optionally attached to the block 4|, to enable various manicuring operations, including pushing back the cuticle, bufhng nails, and Illing the edges of the nails.

Operation of the machine can be described as follows: When the electric motor I9 is put in operation, pneumatic pulsations are transmitted through the flexible tube 28, to the closed chamber 39 behind diaphragm 31. These pulsations cause corresponding vibration of the diaphragm 3l, to reciprocate the block 4|. A particular characteristic of the machine is better understood by reference to Figs. 8, 9 and 10. In Fig. 8 the forward end of the casing 33, is at a distance dl from the cuticle being operated upon, and the tool 44 is being reciprocated to substantially its maximum extent, represented by the distance al. Now as the casing 33 is advanced to the position shown in Fig. 9, the distance d2 becomes considerably less, and also the amplitude of reciprocation a2 is likewise diminished. Fig. 10 shows the casing advanced a further amount, with the amplitude of reciprocation a3 further diminished. Any one of the positions such as represented by Figs. 8, 9 and 10, can be used in practice. In other words there is no critical positioning of the casing with respect to the surface being operated upon. The thrust against the cuticle is slightly increased as the casing is moved forward- 1y, but for any such position the force exerted by the end of the tool against the cuticle is insufficient to mutilate the skin, or to cause pain or discomfort to the subject. It will be evident that this mode of operation is far superior to a. machine having positive drive means for reciprocating the tool, so that the tool is always reciprocated through a stroke of fixed length. Such a machine can be used only with extreme care, and unless held at a critical position with respect to the surface being operated upon, it will cause severe pain and possible mutilation of the cuticle.

The characteristics described above are also utilized when bufling nails or when utilizing a nail file, in place of a tool for pushing back the cuticle. For example if when utilizing a nailfile, the surface of the file should be pressed against the skin, no harm will result, because the file will automatically diminish its amplitude of reciprocation, and will cause no abrasion. Likewise when employing a buffer, if the surface of the buffer should be pressed too hard against the nail, reciprocation of the buffer will automatically diminish or cease altogether, to avoid unpleasant heating.
